Err CF then Err 99 - Canon Rebel XT / Hitachi 4GB Mircodrive

\015 My Hitachi 4GB Microdrive CF card was full. I ordered new (refurbished) ones online. When I put one in my camera the screen read "Err CF". From the menu I selected format > ok. Screen read "Err 99". I tried another one of the new cards, same thing. I put my old CF card back in and deleted a few photos to make room to take more pictures. Everything worked normal. Placed the new refurbished ones back in and got the errors.I have taken the lens off. The battery out. The CF card out. Let the camera sit for 20 or more minutes with all of those items out and systematically replaced them and checked if I got the errors. I was sure to use a fully charged battery. I only got the errors when I used one of the new CF cards. I have cleaned all the sensors. Checked for bent pins. I can't think of anything else. I then returned CF cards to the seller (whom I have bought the exact same thing from in the past and not had a problem) for a replacement. While I was waiting for the replacement cards I ordered a few other CF cards from a different seller. I got them today. Same problem, same errors. Tried all of the same things again and same results. Is it possible that ALL the cards are faulty? Is there a setting on the camera that I have set that prohibits formatting of the CF cards that I am not aware of? If the model number is the same on all the cards is it possible that they are versions that are not compatible with this camera? Any ideas welcome. Thanks.\015

Answers :

Nope, this is not card anymore.

As you know CF is card failure, sometimes this cause to start error 99 , that is lens error , even if there is no problem with the lens.

This happens because the built in software in the camera can get messed up after an error CF.

You fix the problem calling Canon, they will guide through upgrading the firmware in your camera.

First ensure that you are using the camera menu and command to format the new card, and that new cards are properly inserted into the machine.

Call Canon support to get a firmware upgrade.

Was looking through menu options and hit format> ok. It deleted all the pics and Im wondering if there is anyway to get them back. what exactly does format do???

Canon rebel xt eos shows ERR CF. What do I do now?I tried a new flash card but still got the same error message. When I try to preview pictures I have already taken the screen says ¨no image¨. My camera worked for a couple of pictures at one point following this initial error message and then acted up again, showing err 02. It then quickly reverted back to old error CF message.

Check that the pins in the camera that connect to the CF card are clean and not bent. You will probably need a good light and a magnifying glass to see into the card slot. If you can see a pin that is bent you could try straigtening it. BEWARE- turn ...
